Spare Parts Other Motorcycle Parts Accessories Specification Example for City Buses: Racing Spec

This is a worked specification for spare parts other motorcycle parts accessories in a racing spec programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The racing spec version exists because the duty cycle on city buses is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.
